Hello.

Yes, I can see the same problem. Most of it should now be fixed.

Please try updating to the latest svn. I the problem is still here, can
you try playing a video with inigo:
inigo my_video.mpg

Can you see the image ?

I have several ideas to improve rendering usability:

* Allow several rendering jobs at the same time
* Make the rendering process completely independant from Kdenlive, so
that you can close or crash the program without interrupting rendering

Of course, an option to set priority would also be nice, but these
features won't make it in 0.5, because I don't want to delay it more.
Another point is that these things will be much nicer with KDE 4 which
should have a great centralized job progress dialog,
